I recently bought gel kayano 32 because I have a flat foot so my ankles sometimes bend inwards especially during long runs, so I needed a stability shoe.

I currently run a 24:40 5k.

Will the kayanos help me run a sub 20 5k?

I will need to build my running ability but I what I mean to ask is, is it possible?...heard some people say that its not a good shoe for speed work.
